Fig. 3 is a detail view illustrating the manner yoi supporting the attachmentframe .on thel cultivator.' Fig. 4 is a sectional view of the same. Figs. `5"and 6 are details illustrating' the` manner of securing the -attznihment to the-cultivator.

j lnfthe drawings, 2 represents the cultivator-aXl e, having a'carrying-wheel 3 anddrawbar 4, whereto the cultivator or plows 5 are attached* A'bracket' is'secured to one of.v

' the drawebars by means of, plates: 7 and bolts 8,. there beinga series ofholes 9 in the said'- vplates toallow adjustment ofthe bolts to adapt the attachment for' dragbars of different Width. The bracket 6' is upwardly r turned andhas a socket 10, wherein a rod 11 l'14s series ratchet teeth 19 are 'also This rod is provided withanoiifset 13 and is .capable of rotary and longitudinal adjustment in its bearing on the bracket 6 to permit adjusts ment ofthe teeth of theweeding attachment,

thereon. Acollar 16 is secured on the rod 11 by aseo-screw 17 or other suitable means and has alu'g` 18, which projects in under the lframe provided on thesaidgcellar, and a spring 20 is on, the'fra'meil on the 'opposite side'l thereof frointh'e lug 1,8.

'ly claim as my invention- 1. -The combination with a cultivatorV drag-bar, oia bracket secured thereon and provided with a socket, a ro'd havi of an off- 'set and iitting within said socket an having 'a rotary adjustment therein, a weeding dej vice having a series oiteeth mounted on said rod and a' spring coiled about .said rod and arranged to be put vunder tension by the vertical movementci said weeding device.

2. The combination with a cultivator, of a rod mounted thereon, an A-sha ed frame' loosely mounted on 'said'rod an having a series. of teeth,*and a spring having a bearin at one end-of said frameand adjustably hel at its other end, substantially asdescribed.

' v8.; The combination with a cultivator, of a rod mountedthereon, an A-sha ed frame.

loosely mounted on said rod, a col ar secured .on said 'rod and having a lug-projecting under said frame and also having a series of ratchet-teeth, a springA coiled around said rod and having one end in adjustable engagement' with said ratchet-teeth and the other end bearing on the top of .said frame, and a series of weeding-teeth carried -by said 'framerod mounted thereon and extending laterally therefrom," an 'A- shaped frame having-aseri'es of flexible teeth and `aloose bearmgon 4. The combination, 'with a'cultivator,l of a said rodjwhich allows the free' vertical move-.

ment of said frame and a spring device interposed between said frame and rod and engaging the former to hold its teeth in the soil with a yielding pressure, substantially as de- A scribed.

' to bear on said-frame at oneend and having means at its other end whereby the tension of said spring may be regulated, substantially 1 5 as described 6. The com oination, with a cultivator of n rod mounted thereon, a'framc having a series of ieXible teeth and a loose bearing?,r on said rod which allows the free vertical movement of said frame, and a spring device arranged to hold the teeth of said frame in the soil with a yieldingar pressure, substantially as described.

In witness whereof I have hereunto set my hand this 2d day of January, 1906.
